Description

The GdauiTreeStore implements the GtkTreeModel interface required to display data from a GdaTree in a GtkTreeView widget.

gdaui_tree_store_new ()

GtkTreeModel *      gdaui_tree_store_new                (GdaTree *tree,
                                                         guint n_columns,
                                                         ...);

Creates a GtkTreeModel interface with a GdaTree, mapping columns to attributes' values.

As an example, gdaui_tree_store_new (tree, 2, G_TYPE_STRING, "name", G_TYPE_STRING, "schema"); creates a GtkTreeStore with two columns (of type G_TYPE_STRING), one with the values of the "name" attribute, and one with the values of the "schema" attribute.

Note that the GType has to correspond to the type of value associated with the attribute name (no type conversion is done), and a warning will be displayed in case of type mismatch.

tree :

a GdaTree object

n_columns :

number of columns in the tree store

... :

couples of (GType, attribute name) for each column, from first to last

Returns :

the new object, or NULL if an attribute's name was NULL or an empty string

Since 4.2


gdaui_tree_store_newv ()

GtkTreeModel *      gdaui_tree_store_newv               (GdaTree *tree,
                                                         guint n_columns,
                                                         GType *types,
                                                         const gchar **attribute_names);

Creates a GtkTreeModel interface with a GdaTree, mapping columns to attributes' values. For more information and limitations, see gdaui_tree_store_new().

tree :

a GdaTree object

n_columns :

number of columns in the tree store

types :

an array of n_columns GType to specify the type of each column

attribute_names :

an array of n_columns strings to specify the attribute name to map each column on

Returns :

the new object, or NULL if an inconsistency exists in the parameters
